The 361 is a B engine and the year of this one is 1964. I pulled the crank, and rods, etc so its a bare block only. The crank seems to be a stock B forged crank same as a 383 forged unit. Heads are 516's and the rods are the stock forged units found in all the B engines, at least from about 64 on. The rods (I am ASSuming) havent worked as hard as say the rods from a 383 HP motor so hopefully their life cycle has some time left. Bore is std and almost no ridge so I am hoping that supports that idea as well. Thats why I am keeping all the guts. But the block is free if anybody wants it. Set of new .040 cast stock replacement pistons at about $16 on ebay. They would be stock 9:1. Shave a pair of closed chamber 516 heads or bring the block down about .08 and it could make some power, or be a strong propane engine. But at machine shop prices its hard not too go with a larger block for all the $$ that need to be spent. Been pricing out boring, tanking, mag'ing, decking, line hone, bore hone, balancing, and it adds up to some pretty good coin. And it seems its a domino effect...weel, if your going to do that then you should do this...and if your spending that kinda money you had better do these things to be sure everything is right....awwwwwwwwgh.
